gh-pr-visualizer

Visualize open pull requests as a branch tree.

Useful when a repo has lots of open PRs and some of them are stacked on top of each other. Instead of asking:

• which PR depends on which
• which branch should be reviewed first
• whether another branch needs to be synced before merge

you get a quick graph of the actual branch structure.

What It Solves

In bigger projects, stacked PRs get messy fast.

• review order gets unclear
• dependency chains live in Slack messages or PR comments
• it is easy to miss that one PR is based on another feature branch instead of main
• reviewers and authors waste time figuring out what needs to land or sync first

This tool pulls open PRs, infers parent/child relationships from baseRefName and headRefName, and renders the stack as a tree so you can inspect the structure at a glance.

Features

• visualizes open PRs as a tree based on actual branch relationships
• shows root branches, tree depth, visible PR count, and review-state counts
• search by PR number, title, branch name, author, or review status
• focus a subtree when you want to review one stack in isolation
• collapse or expand subtrees to reduce noise in large graphs
• open an entire PR chain at once with Open review batch
• copy the current branch name of the selected PR
• copy the full list of PR links for the selected subtree
• inspect review facts, focus path, and mini timeline for the selected PR
• refresh live data from GitHub without restarting the tool
